What's wrong with my Qt Creator??

Well, I downloaded and Installed Qt Creator for Windows from qt-project.org/downloads, but I can't see the "examples" area, I can't create most types of projects, so I'm unable to do pretty much anything, and I don't know why.

So, I first guessed that too, so I got a license and downloaded and installed the Qt Libraries for windows 64 bit, and from that I got the Qt Designer and the Qt Linguist, but nothing about the Qt Creator...

It wasn't necessary, but ok. Did you removed previously installed Qt Creator?
If not, now it should find your new libraries automatically and work well. If you already removed it, try to install it again without removing your libraries.

Don't give up, you could try to check setting and set up yours, if Qt Creator have some problems with settings autodetection:
launch Qt Creator and go to: Tools > Options > Build & Run, make sure there are no problems here.
Check out this documentation "QtCreator : Adding Kits":http://qt-project.org/doc/qtcreator-2.7/creator-targets.html
Good luck!

I forgot to say that when trying to create a new project or file (simple plain c++ code or something like that) I get a message telling me that there are no kits, so I think my Qt creator 2.7.0 (the only Qt Creator I found available for download) came with no valid kits.

No, he said after downloading Qt Creator IDE he also downloaded Qt libraries
